George Williams Lyman (December 4, 1786 – September 24, 1880) was an American industrialist and later described as one of the Boston Associates for his pioneering work in establishing textile mills throughout Massachusetts, and was one of the founding directors of the Hadley Falls Company which established Holyoke, Massachusetts.

[1][2][3][4] The son of merchant Theodore Lyman, he worked for his father's business and continued trade with Europe, China and the West Indies until the Embargo Act of 1807 and War of 1812 forced him and his family to find new business pursuits.

[1][2] He also worked with inventor Erastus Brigham Bigelow to secure patents for his Ingrain carpet power loom under the Lowell Manufacturing Company.

[1][4] Being his father's eldest son he inherited the Lyman Estate, "The Vale", in Waltham, Massachusetts, and took key interest in maintaining its grounds and gardens, often hosting members of the public.

[1] He was also a prominent supporter of the Boston Athenaeum, backing a number of its acquisitions during his life.
